Design Merchant Experience, Checkout configuration on Request Network dashboard

[rodrigopavezi]

We should allow Merchant to configure their checkout setup with smart accounts as operators

The actual feature will use smart accounts, but this issue is only the design and is not blocked by smart accounts.
